Previous behavior which may be useful for moving-mesh cases can be
selected using the optional entry:
writeTotalArea yes;
The initial total area is written in the log and data file header e.g.:
# Source : faceZone f0
# Faces : 8
# Area : 1.063860e-02
This allows checkMesh and other mesh manipulation utilities to operate
on the mesh without any time directories being present.
Also renamed option zeroTime -> withZero for consistency with the noZero option
This approach simply accumulates data outside the range of the bins into
the first or last bin which may be OK for small motions. For larger
motions it may be better if the bins are updated or operate in a
coordinate system attached to the body for solid-body motion.
